Specvication of Letters Patent. Application led April 23, 1910.` SerialNo. 557,163.

. Patented Mar. 7,1911.

To all whom 'it may concern:

Be it known that We, CHARLES H. ODEN- BAUGH and CHARLES A. CRARY, bothcitizens 'contemplated -by our invention.

of the United States, vand residents of Middleport, Meigs county, Stateof. Ohio, have invented certain new and useful- Improvements in Pipes;and we do declare the following to be a clear, full, and exactdescription of the invention, attent-ionbeing called to the drawingwhich accompanies this application and forms a part thereof.

p This invention relates to improvements in smoking-pipes and the ob]ectof the invention is to construct pipes 1n a certa-1n manner.

which counteracts their tendency to become excessively hot, so that thesmoke 1s cooled 4before it entersthe users mouth.l

away, a pipe provided with features used.

1n connection with-'our invention. Fig. 3, shows in a similar view apipe improved as Figs. 45 andv 6, the. latter two cross-sections of thefirst, illustrate at enlarged scale a member entering in theconstruction of the pipe as shown in Fig. 3. y A In the drawing, Aindicates the bowl of lthe pipe of usual form and construction.

B is the stem thereof and G is the mouthpiece of it. y v

In pipes as now used, the air is drawn in through the open top of thebowl-where it is subject to vthe effects of heat as soon as itenters-between the-hot side ofthe bowl. It becomes further heated whilepassing through the hot ashes of consumed tobacco and through the zoneof combustion where the tobacco is burning. In this highly heatedcondition it passes through the stem ofl the pipe with little chance ofbeing cooled. before it reaches the smokers mouth.

. We prevent the preliminary heating of the air by `admitting it atthe-zone of combustion, so that the air need notv pass through the hotbowl, nor through the hot ashes of consumed tobacco. Conduits .throughwhich the air moves after it has passed-the point of combustion arelkept-l coolby free admission of air and byprovision of means wherebythe heat is dissipated by favoring its radiation. For such purpose theWall of the bowl is' foraminated, the openings a whereby this effect isobtained being closely spaced and of asuitable shape. In Fig. 2, theseopenings are. shown circular and in Fig. 3, they are .in form'of narrowslots.

The tobaccois in form of a plug or car- Y tridge D of a size adapted tosnugly -ll the bowl. It is surrounded by a wrapper Z of suitablecombustible material without a bottom and adapted to be consumed withthe tobacco. This may be cigarette paper or a tobacco-wrapper analogousto the wrapper of a cigar.

The cartridges may form an article of `commerce and be. manufacturedready for use, or the wrappers, particularly if of pa.- per, may bemanufactured ready for filling with tobacco by the user wheneverrequired. The object of using this wrapper is not so much for thepurpose of confining the tobacco to form the plug or cartridge, as forthe purpose of producing a closure for the air-inlet-openings rz in thebowl and below the point of combustion, since admission of air below theburning tobacco would int-er-` fere with the draft. Air may always enterat the point of combustion, since the wrapper burns away with thetobacco and following the burning zone, rendersy the perforations open.Therefore when the complete cartridge is not manufactured ready for use,the mostconvenient way of procedure is to use the wrapper as a-liningfor the side of the bowlby inserting it into the same, after which thetobacco is 'filled in. In this case the liningmay be 'inform of a shorttube', or in sheet-form merely, and it may be manipulated in, anysuitable way, with or without an appliance to placeit to a seat. air tothe tobacco which prevents its preheating, thev bowl of the pipe is alsoprevented'from accumulating heat by reason of its perforated wall.Furthermore any heat absorbed by this wall is againquickly dissipated bythe. free access of air to it above, as well as below the point ofcombustion. Accumulation of heat in the stem is also Outside of thisdirect admission of' counteracted by means which favor dissipation byradiation. These means consist of disks E of a material which is a goodheat conductor. Any metal, preferably aluminum, `may do. These disksareperforated to permit'mountinfr upon the stein', and they :1re ofgraduated diameters, as best shown in Fig. 3, so as to conform to theusual shape of a Vpipe-stem. They are spaced apart by suitable spacingmeans e which may consist of short collars, or washers and interposed`between adjoiningr disks, or form integral parts thereof as shown 1nFig. 6. These spacing means may also be obtained by; the

provision of projections as shown in Figs. 4

These dlsks may also form integral and 5. annular ribs which projectfrom the stem.

` Having described our invention, we claim as new:

l. A pipe having a foraminated bowl in combination with a combustiblelining closely fitting the interior of said bowl.

2. A pipe consisting of a bowl and of a stern and of heat-dissipatingdisks mounted upon the stem with spaces between them, 25 the diametersof these disks being-graduated to produce the outline of the stem inproper shape. l

Intestimony whereof, we hereunto aiix our signatures in the presence oftwo wit- 30 nesses CHARLES H. ODENBAU GH. CHARLES A. CRARY.
